#1 - Should be available from the beginning of the game, as soon as you enter the village.. Maybe you just did not buy it back from the underwear thief in the back alley? You need to buy almost all pairs of underwear back from him, with the exception of those you get when you reach full affinity with one of the main NPCs. He's in the alley at night.

#2 - Repair the weapon shop

#6 - Repair the smithy

#7 - Repair the carpentry workshop 

#8 - Repair the library

Edit:

- You need to repair the weapon shop in order to be able to get the quest to repair the smithy, and you need to repair the smithy and save the relevant villagers in order to get the library/carpentry workshop repair quests.
